Why is my cat hissing at her 3-month-old kittens? What can I do?

If the kittens are old enough to survive on kitten food instead of needing to nurse (around 8 weeks) then I would not be too concerned. Mama may just be teaching them cat manners. If the kittens are younger than that and still dependent on mom for milk, then I would contact your vet, as it is important that they are getting enough nutrition, or they could quickly become ill. It's also important to have mama cat checked to make sure she isn't feeling unwell as sometimes conditions like mastitis (inflammation in the mammary glands) can lead to a mother cat refusing to allow kittens to nurse. I hope that helps!

If she is hissing at him just occasionally, it's not always a bad sign as it may be because the nursing is hurting her but if this is constant she might be rejecting him. in that case you will have to separate them and feed the kitten yourself with kitten milk replacer.

It is normal. She is telling them that she taught them everything they know and now it is time to leave and be adults. She is basically weaning them. So let her deal with it. You can try to find homes for the kittens now. They do not need their mother anymore. It is also possible that Oreo is pregnant again and ready to have new kittens and therefore decided that it is time for the older kittens to go.

The kittens should be weaned at 6-8 weeks. Not all animals are natural, nurturing mothers, and she may just not know how to make the kittens go away. I would recommend separating them. The kittens still need a safe environment and easy access to kitten food, but they no longer need mom for milk.

Sannu is probably close to giving birth, and she can act aggressive during this time. You need to put Sannu in her own room with a birthing box, food, water, and cat litter. She needs her own space as well as peace and quiet. Do not let the other kittens into this room until the kittens are at least 4 weeks of age.

Hello, sorry to hear about your kittens. If mom was away from the kittens, if she had a bath, or if the kittens had a bath then they could be having a hard time recognizing their smells. If this behavior continues then you may need to separate them and reintroduce them slowly. Otherwise, keep an eye on them and make sure that they are not fighting too often. Hope this helps and best of luck.

This can happen after a stay at the veterinary clinic. It should pass in a few days as Stella loses the scent of the clinic. You can try a pheromone product, such as Feliway spray or plug in diffuser, to decrease any anxiety.
